互通式立交变速车道及分流鼻处设计关键点浅析

Elementary Analysis of Design Key Points at Speed Change Lane and Distributing Spot of Interchange

该文指出互通式立交设计往往局限于满足规范要求就是满足了安全要求,设计者经常忽略运行过程中驾驶人员的心理、生理方面的感受以及车辆的行驶特性等。往往是满足规范的单个指标在某些场合组合在一起时,可能出现不安全因素。变速车道及分流鼻处的设计尤为如此,因此,在立交设计中应给予足够的重视。

The article points out that the interchange design is limited at meeting the criterion requirements sometimes, that is to meet the safety requirement. The designers often neglect the psychological and physiological feelings of the drivers and the running characteristics of vehicles in the course of driving. The single index meets the standard in some combined situations sometimes, but the insecurity factors possibly appear. The design of speed change lane and distribution spot are especially so. Therefore, it should be to pay sufficient attention to the design of interchange.
